This paper reviews the theoretical concept of "Effecient Market Hypothesis" and introduces new concept of "Fractal Market Hypothesis". According to this hypothesis the returns follow a biased random walk called a Hurst persistent process which is characterized as long memory process. Testing this concept on Czech stock market index PX50, the (R/S) analysis was carried out and the Hurst exponent was calculated. It finds out that stock returns of PX50 follows a persistent Hurst process with Hurst exponent of 0,662. This is significantly different from the value for a random walk and it is corresponding to results of other researches done before.
Keywords: fractal market hypothesis, Hurst exponent, Hurst persistent process
